After the software update 16th of sept. 2020 my Edge 530 really have a problem to register tunnels. Pre update it missed like 10% of a tunnel at most, now it usually misses the whole tunnel plus a few hundred meters after the tunell, depending on my speed. This mess up the workout as every data gets wrongly calculated. Anyone know how to solve this? PS my CAT phone with Strava app register every meter very accuratly, so it'sn nothing wrong with GPS signals. Just in case you wonder, yes it's legal to bike these tunnels.
